Abstract (en)
[origin: WO9012972A1] In a sampling valve comprising a stretchable hollow valve plug (10) mounted on the front end of an axially displaceable valve stem (7, 8), the plug is provided on its inner surface with a bead (14) projecting into a groove (15) in the stem without influencing the stretching and retraction of the plug. When the stem is withdrawn from the valve body (1) for inspection or other purposes, the plug is carried along due to the engagement of the bead (14) with a side wall of the groove.
